ʻO nā mea hoʻopili uila ma ke kālā ke kumu nui o nā huahana uila.Me ka hoʻonui mau ʻana o ka laulā noi, ke hoʻonui nei nā koi o ka hana - ʻaʻole hiki ke hoʻohui ʻia ka mea pili i ka wā o ka haki ʻana, a ʻaʻole hiki ke hana i ka piʻi kiʻekiʻe loa;mālama i kahi kū'ē haʻahaʻa a paʻa i ka wā e hoʻopili ai;kiʻekiʻe ʻaʻahu kūpaʻa a me nā mea ʻē aʻe.

No ka mea hiki i ka mea AgCdO ke hoʻoheheʻe i ka lawe ʻana i ka wela a me ke kinai ʻana i ke arc i nā wela kiʻekiʻe, ua lōʻihi kona ola uila.ʻIke ʻia ʻo "universal contacts", ʻo AgCdO hoʻi he haʻahaʻa a paʻa ke kūpaʻa pili, a maikaʻi hoʻi ka hana hana.He ʻeleu ia ma nā ʻano ʻauwaʻi liʻiliʻi a hiki i ke au nuinā hoʻololi, nā relay, nā mea hoʻopilia me nā uila ʻē aʻemea pili.Eia nō naʻe, he pōʻino make ko AgCdO he mea maʻalahi ka hana ʻana i ka mahu Cd, a he mea ia e make ai ka Cd ma hope o ka inhalation, e pili ana i nā hana o ke kino, e hōʻino ai, a e hoʻopilikia ai i ke kaiapuni.No laila, ua hoʻokomo kekahi mau ʻāina ma ʻEulopa i nā kānāwai a me nā hoʻoponopono e pāpā i ka hoʻohana ʻana i nā mea hoʻopili paʻa CD i nā mea hana hale.

ʻO ka nickel kala ka mea hoʻopili uila maʻamau i hoʻohana ʻia i ka contactor a me nā relay.He maikaʻi ka uila a me ka thermal conductivity, haʻahaʻa resistivity a me ka piʻi ʻana o ka mahana.A loaʻa iā ia ka ductility maikaʻi a me ka hiki ke ʻokiʻoki, ka pōʻai pōkole pōkole, nā uku haʻahaʻa haʻahaʻa.Hoʻohana nui ʻia ia i nā kamaʻilio kiʻekiʻe, kiʻekiʻe-koʻikoʻi, uila, automotive a me nā ʻoihana ʻē aʻe a me nā kula.

Eia nō naʻe, ʻaʻohe infiltration ma waena o ke kālā a me ka nickel, a ʻo ka pilina ma waena o ke kālā a me ka nickel i hana ʻia e ke ʻano hana metallurgy pauka maʻamau he maʻalahi mechanical contact.A ʻoi aku ka maikaʻi o ka machinability me ka piʻi ʻana o ka ʻike nickel.E ʻike ʻia nā māwae manawa i ka hana ʻana i nā mea kālā-nickel me nā mea nickel kiʻekiʻe, ʻaʻole i pili wale i ka machinability o nā mea, akā pili pū kekahi i ka machinability o nā mea.A e hoʻopili hou ia i nā waiwai uila o ka mea.

I mea e hoʻomaikaʻi ai i ka pilina o nā pauka ʻelua, ua uhi ʻia ka mea hoʻololi ma ka ʻili o ka pauka nickel ma ke ʻano o ka hoʻohui ʻana i ka kemika a me ka hui ʻana i ka pauka, i mea e hoʻoponopono ai i ka pilikia ʻaʻole i hoʻokomo ʻia nā pauka ʻelua.

ʻO kēia kaʻina hana e ʻoi aku ka poepoe o ka ʻili o ka pauda nickel, hoʻomaikaʻi i ka pilina ma waena o ka pauda kālā a me ka pauda nickel, a ʻaʻole ia he hoʻopili mechanical maʻalahi;Hoʻomaikaʻi ʻia ka hana ʻana o nā mea nickel kālā, ʻoi aku ka maikaʻi o ka elongation, a ʻoi aku ka maikaʻi o nā waiwai uila.
